I could feel it through everything at all rpm to varying degrees but it had a really rough patch about 5000rpm.

By any chance, where you able to juggle the engine by hand at rest? as a test? or had to remove the bolt to have a look?

I could feel something was loose when I tapped the bars with a hammer  :002: I was surprised because it felt tight when I checked but when I took it out I discovered the thread lock.

The service schedule for the Inazuma has a list of bolts to check for tightness, amongst them are some of the engine mounts and exhaust bolts. The same for my other bike. Every so often I find one or two needing a tightening so if they have never been checked that would be a problem.

Hello,

Have not been able to identify the problem Im afraid...  :012:

Still got to check those engine mounts closer, but I did have an an inspection and they looked good.

Still waiting for sprockets, chain and clutch plates to arrive. I have the sinking feeling though, thats not it.

Watched a video of a RMZ250 engine teardown and overhaull.. yikes! I would love to do that one day... but don't have the tools or the time ATM.

I also looked at general engine trouble... a close resemblance to my issues seems to be the crankshaft bearings... I really hope not.

Thing is that I don't see any worthy workshop up to the task of a full engine overhaul over here, not to mention the price tag!!!

Any other ideas? idles fine, no trouble starting, no perceivable loss in power.

On another front, are you able to get lightly used engines from ebay into
Chile at a reasonable price?  Swapping entire engines doesn't require
a ton of mechanical skill since you don't have to open anything up, so is
probably something you would not need a shop for.

Good luck.
